摘　　要：以某电厂填顶高程170,180,230 m灰坝的模型为研究对象,基于基本动力特性试验,进行了在有干滩和无干滩两种工况下模拟Ⅵ度与Ⅶ度地震烈度的响应试验和破坏试验研究,同时对用3种不同灰渣拌合料加高的180 m高程灰坝模型进行了抗震性能做出评价。研究结论对灰坝抗震理论的研究和减震防灾具有一定的指导意义。Based on the former achievements and the known basic dynamic property of fly-ash dam, earthquake response tests of VI and Vll degrees simulation earthquake waves and failure tests have been done on the models of fly-ash dams with different dam crest elevations of 170, 180, 230 m by the large-scale shaking table, The earthquake resistance tests have been done on the models of ash dams heightened by three mixtures of ash and corresponding evaluations are given, The conclusions are beneficial to the research of earthquake resistance of ash dam and the earthquake attenuation and disaster prevention.
